ORE-SEPARATOR.

Specification of Letters Patent.

Patented Sept. 4;, 1906.

Application filed December 8,1905. Serial No. 290,948.

of Kansas, have invented a new and useful. Ore-Separator, of which the followingis av specification.

This inventlon relates to ore-separators. The ob ect of the invention is to provide a machine which shall be simple of construction, of the highest efliciency and durability in use, and which will with rapidity and certainty separate the noble metals from the gangue, conserve the former and discharge the latter.

better understood, the same consists in the novel construction and combination of parts of an oreseparator, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a view in side elevation, partly in section, of a machine constructed in accordance with the present invention. Fig. 2 is a similar view of the rear portion of the machine, exhibiting certainparts omitted in Fig. 1. Fig. 3 is a transverse sectional view, on an enlarged scale, taken on the line 3 3, Fig. 1. Fig. 4 is a longitudinal sectional detail view of part of the actuating mechanism. Fig. 5 is a transverse sectional view taken on the line 5 5, Fig. 1, and looking in the direction of the arrow thereon. Fig. 6 is a perspective detail view of a scoop or paddle used in connection with the apparatus.

The separatingmechanism embodiesinpart two metallic troughs 1 and 2, which are semicircular in cross-section, and each is provided with a curved lip 3 and 4, respectively, the lip 3 projecting over the edge of the trough 4 and serving as a conductor for directing the flow of material thereto. The troughs are supported on wooden bases 5, that are concaved on their upper faces to conform to the shape of the troughs, which are supported upon a rocking frame comprising two bars 6, (more clearly shown in Fig. 7,) which are fulcrumed intermediate of their ends upon a shaft 8, that projects through the sides of a frame consisting of two side pieces 9 and end pieces 10, the frame being supported by four uprights 11 that rest upon a platform 12 beneath the machine. The bars 6 carry two pillars 13, (more clearly shown in Fig. 4,) the upper face of each of which is provided with a recessed head 14, in which is arranged a rubber buffer 15, having combined therewith a metallic facing 16, the said facings being designed to be engaged by polygonal wheels 17, carried and driven by a shaft 18, one end of which carries a pulley 19, around which passes a belt 20 to a suitable source of power, and the other end of which carries a sprocketwheel 21 and a crank 22. It is designed that the machine may be operated either by hand or power, and for this reason both. the crank 22 and pulley 19 are provided. It will.

1 be seen that when the shaft 18 is rotated l/Vith these and other objects in view, as will appear as the nature of the invention is the faces of the wheels 17 will cause the bars to be alternately depressed and raised, thereby imparting a vibratory motion to one of the troughs and causing the contents thereof to be thoroughly agitated.

Working within the-two troughs are cylinders 23 and 24, the former of which is a hollow metallic structure and the latter awooden roller provided with radial incisions 25 to pre vent warping and bending, the periphery of the cylinder 24being covered by sheet metal, preferably sheet-steel 26. To the periphery of these cylinders are secured scoops or paddles 27, (shown in detail in Fig. 6,) the same being constructed of metal and provided with side and end flanges 28, to be secured to the cylinders.

The shaft of the cylinder 24 has combined with it a sprocket-wheel 29, around which passes a sprocket-chain 30 to and around a sprocket-wheel 21 on the shaft 18, whereby the said cylinder is directly driven from the source of power, the shaft 32 of the cylinder being mounted in suitable bearings carried by the side piece of the frame. The shaft 33 of the cylinder 32 carries a sprocket-wheel 34, around which passes a sprocket-chain 35, to and around a sprocket-wheel 36, carried by the shaft 32.

The trough 1 has adjacent to its lip 3 an orifice 37, that discharges into a pipe or tube 38, which empties into a pan 39, disposed on the base of the machine and being preferably porcelain-lined, the pipe being a water-overflow pipe to keep the water in the trough 1 at a predetermined level.

bottom of a tank 41, the tank being supplied with water by a pipe 42, that connects with a pump 43, the pump-rod 44 of which is driven by an eccentric 45, carried by the shaft 32, as

\Vater is supplied to the trough 1 by a pipe 40, which enters the IIO clearly shown in Fig. 2. ater is supplied to the pump from a tank 46, disposed under the base of the machine and receiving its supply from the water in the pan 39 and from water carried over with the gangue or refuse, the object being to conserve the water and use it over and over again, thereby to render the machine peculiarly adaptable for use in localities where water is scarce. The pan is provided in its bottom with one or more openings 47, beneath which is arranged a pipe 48, that discharges into a filter 49, containing a partition 50, one half of the filter being perforated and the other half being imperforate, and into the latter portion the pipe 47 discharges, as elearly shown in Fig. 1. Any gangue or metals entering the filter will be retained by the partition 50 and may be removed from time to time, the water passing through the partition being filtered through a lining of any suitable material and discharged through the openin s 51 into the tank 46, the

filter being disposed in the tank as shown in Fig. 1.

Ore is supplied to the trough 1 by an endless conveyer 52 of the usual or any pre ferred construction, at the feed end of which is a hopper 53, having at its bottom a cut-off 54, by which the supply of material to the conveyer may be readily controlled. This hopper has a vibratory or jigging motion imparted to it through the agency of a rod 55, one end of which is connected to the hopper and the other end to a stub-shaft 56, carried by a casting 57 on the under side of one of the bars 6. Arranged beneath the upper end of the conveyer is a screen 58, which is arranged in a trough 59, supported for shaking movements by hangers 60, secured to the upper frame-beams 61, and by rods 62, pivotally connected with the under side of the trough and with the bars 6, as clearly shown in Fig. 1. It will be seen that by imparting a vibratory and shaking motion to the screen 58 the finer materials supplied thereto will be caused to sift through the screen and be carried by the trough 59 down into the trough 1, the coarser materials that do not pass through the screen being discharged down chutes 63 and 64 to the platform. In order to prevent the finer materials that pass through the screen from being discharged beyond the trough 1, the lower end of the trough 59 is provided with a deflector 65, which will cause the said materials to be directed positively to the trough 1.

The conveyer 52 receives motion from a cross-belt 66, which engages a pulley 67 on the shaft 33 and a pulley 68 on a shaft 69, which is supported by hooks 7 O in the under side of the beams 61, the said shaft carrying sprocket-wheels 71, that are engaged by the members of the conveyer, that portion of the conveyer beneath the hopper being in engagement with the sprocket-wheels 72, carried by a shaft 7 3, mounted in journals of the frame 74, that supports the hopper.

The shafts 18, 32, and 33 are journaled in bearings carried by bars 75, connected by cross-bars 76, and one end of each of the bars 75 is hinged at 77 to a cross-bar 78, as shown in Fig. 1, the opposite end of the bar 75 being projected beyond the frame 10 and provided with handles 79, the object of this arrangement being to permit of the bars, and with them the two cylinders 23 and 24, being lifted to the position shown by dotted lines in Fig. 2 for the purpose of removing any metalin the trough.

In operation the material fed to the trough 1 is thoroughly agitated and bodily forced over by the scoops 27 into the trough 2, which, as before stated, contains a body of quicksilver, and the sand or fine earth is forced through the body of quicksilver, which will take up the bulk of the noble metals, and the material is discharged down a chute 80, which is supported by the bar 6 and by the beams 11 and falls into the pan 39. Of course there will be more or less water carried over with the tailings or refuse, and this will escape down the pipe 47 into the filter, thence to the tank 46 after being filtered, then to the tank 41 and back to the trough 1. Any goldbearing earth that passes to the filter will, as

before stated, be retained and may beremoved from time to time and treated by any of the well-known processes to remove any residual gold, and the same process can be observed with relation to the gangue that passes to the pan 39.

It will be seen from the foregoing description that by the arrangement of the parts described thorough and rapid handling of dry earth or sand may be effected and that the heavy gold contained therein will with certainty be separated.

Having thus described the invention, what is claimed is 1. In an ore-separator the combination with a rocking frame, and a trough support ed thereby of a rotatable polygonal wheel, a column supported by the frame, a cushion thereon contacting with the wheel, said. wheel adapted to vibrate the column and frame, and a trough carried by the frame and movable therewith.
